Deep in the urban jungle, mental decay and sensory overload wear at a man weary from the ever-strengthening tide of images and emotions that wash over him in on a daily basis in director Maria Procházková's expressionistic character study. To walk by Mr. Seman (Oldrich Kaiser) on the street would be to walk by your average, slightly disheveled middle-aged man to most city dwellers, but a closer look reveals a troubled soul unable to cope with the increasingly intrusive outside world. Relishing in the company of a sympathetic neighbor and her kindly daughter and eager to chat up strangers on the street in the daytime hours, Mr. Seman spends his nights constructing wondrous creations from the neighborhood trash. While his friendly demeanor endears Mr. Seman to those willing to stop on the sidewalk and give him a moment of their precious time, the hallucinations that plague Mr. Seman's vision and the so-called "shark in his head" prompt concerned officials to consider the prospect of institutionalization.
